Polish day-ahead baseload power increased 3.4 percent to
217.56 zloty (54.33 euros) a megawatt-hour, according to
Bloomberg calculations based on Polish Power Exchange data.

Electricity demand advanced as much as 5 percent this week
to almost 25,000 megawatt-hours during the evening peak, load
data from the Polish power grid show. Prices in neighboring
Czech Republic and Germany were higher, making Polish
electricity attractive for buyers in those countries.

Midday temperatures in Warsaw next week may be as low as
minus 12 degrees Celsius (10 degrees Fahrenheit) from minus 6
degrees today, and minus 15 on Dec. 1, according to
CustomWeather Inc. data compiled by Bloomberg. That may keep
demand for heating and power output from co-generation stable.

Power supply is forecast to increase by about 200 megawatts
of capacity scheduled to start in the coming days, according to
the grid data.
